ROADREBAL'RING MACHINE.

Application filed February 24, 1926.- Seral No. 90,35?.

My invention relates generally to machines for use in road construction and maintenance work and has. in vview more particularly ay device whereby irregularities and depressions in a road are automatically filled up and graded.

It is an object of my intention to provide posited in ysaid depression or irregularity.

A further object of lmy invention is to provide means whereby theI size or depth of the depression or irregularity in the road will govern the rate of flow of material into the depression or irregularity so that uniforni motion of the vehicle along' the road is possible.

lith these and other objects in view as will hereinafter appear, my invention eon` sists in the construction arrangement and combination of the various parts of my device, whereby the objects contemplated are attained. As hereinafter more fully set fortlupointed out in my claims, and illustrated in accompanying drawings, in which:

Figure 1 is a vertical cross sectional view of my invention. i

Figure 2 is a plan yview on the section lines 2-2 of Figure 1 looking in the directions of the arrows.

Figure 3 is a vertical cross sectional view on the lines 3 3 of Figure 2 looking in the ,direction of the arrows.

In the drawings similar reference characters refer tolike parts in thevarious Figures.

Referring to the drawings and 11 indicate two skids having cross bars 12 and 13 for bracing theksame. Upon each skid are two supports 14 and 15 eachv of which is composed of a series of blocks superposed upon one another lhaving the `front ends thereof, terminating in staggered relation, so that the elevation of mydevice,- with relation to the skids and the roadv may be varied at'will. j

Extending between the supports 14 is a supporting member 16 and Vextending between the supports 15 is a supporting memr ber 17 upon which my entire device rests.

The ends kof Athesupporting members 16 and 17 terminate in downwardly disposed U- shaped ends 18 which are adapted to rest upon the staggered portions of the supports 14 andl. e

Resting upon the members 16 and 17 and secured thereto in any desired manner are the horizontally .disposed members 19 and 20, which are placed close to the ends 13 of the supporting members 16 and 17. Rising from the member 19 are the standards 21 and 22 and from the member 20 the standards 23 and 24. The standards 21 and 22 are joined at their tops bythe member 25 and the standard 23 and 24 are joined by the member 26. Extending between the horizontally disposedv members 25 and 26 are the bracing bars 2, 28, 29 and 30, while the members 19 and 20 are braced by the bars 31, 32 and 33. Instead of the above described form of supports and bracing,

any other suitable type of construction may 37 which is adapted to roll along the sur.

face of the road and into any depression in the road. To the other-.endof the trigger bar a metal loop 39 is pivoted in any suitable manner and through this loop passes a cable or rope 38 which then leads over two pulleys 40 secured upon the horizontally disposed bar 41. From the pulleys 40, both ends of the cable extend over the pulleys 42 which are also attached to the bar 41. The ends of the cable 38 are fastened to two weights 43, whose function is to keep the roller 37 in constant Contact with the road.`

Between the point where the trigger arm.

36 is pivoted to the brackets 34 and 35 and the end of the arm to which the loop 39 is located, a lifter arm 4 4, is pivotally secured to a block 46, which is secured to the vertically disposed plunger lifting rod 47.

Extendingbackwards from the block 4G is a plate 48 which may if desired be integral with the block 46 from which extend the horizontally Adisposed plunger lifting pins 49, which pass through the series of plungers 50. A

The plungers 50 are Vdisposed in a tank 51 and the lower ends thereof act as valves for the o] 3enings 52 providedin the bottom of the tank. Supported from `the walls of the tank 51 is a guide cage 53 lim-*ing aligned openings in which the rod 4i" and the plungers are adapted to reciprocate.

An extension ot the tank :il ext ends over a .tire box Bit whereby the tar, oil or other substance used in repairixigr, may he heated so that it, will have the proper consistency to (low easily or be swayed hy air pressure.

The embodiment shown in the present application shows a battery olz eight planetas. but it seflwerdent that the number of the planners may be varied and also that a duplicate battery having its own trigfjn'er arm may be disposed in alignment with that shown in this embodiment.

Secured to the two central plunger-s ol' the back set of Four plungers are the arms` 55, which terminate in a horiz/.ontally dis posed portion 5G having; an aperture 5T therein.

Immediately in back ol' the plunger hat tery are two bins 5S and 59. flhe bin ."ftv is adapted to contaiil small aggregate and the bin 59 contains a larger .sir/.e aggregate. The openings oit the bins and Fill are lilaced one above the other as shown in Fie ure t and the hin 5S is closed by the sliding:- door 60 haringV rod (it attachent thereto, which passes through lthe aperture 5T in the member 56 and terminates with an enlarged head 62. The door 63 ot the hin 50 'terminates in a right angular portion (ilharing' an aperture 65 therein through which the rod 6l also passes.

Disposed above the tank 5l is a reservoir (itl which may it desired be carried ou a truck or trailer for the tank 5l and the .reservoir has a pipe 6T leading: to said tanti and a 'alie 68 normally open in the pipe to lill control the flow ot material to the tanlc al. The reservoir 6G is placed far enough above the planners 5() so as to allow the proper reeiprocation thereof.

If desired reservoirs for the bins and 59 may also be placed upon my device or may be carried by a` trailer.

`The doors 6() and 6l are inelosed in a U-shaped guard 69.

The Weights 13 are adapted to recipro cate in tubular members T0 which are tastened to the brace bar il() or on any other suitable part of the machine and serve as guides for the weights.

A hook '71 is secured to the brace bar and is adapted to hook over the bar 36 when it is desired to hold the parts in inoperative position.

The operation oit my device is as follows. The, entire central machine is adjusted upon the staggered blocks lil and la so as to properly adjust the roller 3T with relation to the road. Upon the roller 37 striking a depression the weights 43 will cause the roller Si' to descend into the depression and the bar @tl will move the plunger lifting' rod 4:7 and with it the plungcrs 50 upwards.

This will lu'ieover the openings 52 and tar will he deposited in the fflepression. Upon the upward movement ot tho planners 5l) the arms will raise the. rod (il carrying with it the door (30 of the bin 5S and small anw-errate will he depositeil upon the tar. la case a deep depression is encoiuitered the upper portion T2 oi` the door (lll will encounter the over hanging portion (lit of the door ll and largre aggregate will also be deposited. lfpon the roller iii' ascendingnr out oi' thc depression the bar -L`ll will more the planners 5l) down vard and close the openings 32 thereby shutting oilk the llow of tar. lt the saine, time, the hars 55 more dow.n ward and the doors (i0 and (5lclose by ,egraritr It desired nuts may be placed upon the bar (il in order to compel the closinp oi? the doors G0 and GS.

lllhenerer the supply olf tar in the receptacle (3G is low the valve G8 may be closed and a new supply obtained :for the reservoir (iti.

'lhe whole device adapted to he drawn upon the skids hy horses or any other means atomeV the road that to be repaired. ll is evident that the skids l() and itl may be provided with wheels or rollers if desired.

idoine changes may be made in the construction and arrangement of my invention above .set :lorth without departing .from the real purpose and spirit thereof, and it my intention tio corcr by the :following claims, any modii'ied forms oit structure or use oit mechanical eqn' talents, which may be reasonably included within their scope.
